I'm using Tostran pump and advised by C&W to use it on alternate days. I found it took about 8 weeks to make a noticeable improvement, and that has been mainly in feeling more resilient generally, more decisive and clear headed. I wouldn't be without it now. I just feel more like my old pre menopausal self. Not much change in libido sadly.
I have had levels checked (testosterone, SHBG, free androgen index) and these have been OK. But also been told that blood tests are pretty meaningless, as not enough research to know what the levels should be for women, and better to go by symptoms. Also, warning signs of too much are a spotty back and being aggressive!!
I'm now having to switch to Testogel soon as cant get Tostran. Have been told to use this daily and make a sachet last 7-10 days. Have also used Testim in same way, when it was available.
